Policy List

Last updated for Chromium 38.

Both Chromium and Google Chrome support the same set of policies. Please note that this document may include policies that are targeted for unreleased software versions (i.e. their 'supported on' entry refers to an unreleased version) and that such policies are subject to change or removal without prior notice.

These policies are strictly intended to be used to configure instances of Chromium internal to your organization. Use of these policies outside of your organization (for example, in a publicly distributed program) is considered malware and will likely be labeled as malware by Google and anti-virus vendors.

These settings don't need to be configured manually! Easy-to-use templates for Windows, Mac and Linux are available for download from http://www.chromium.org/administrators/policy-templates.

Note: Starting with Chromium 28, policies are loaded directly from the Group Policy API on Windows. Policies manually written to the registry will be ignored. See http://crbug.com/259236 for details.

Starting with Chromium 35, policies are read directly from the registry if the workstation is joined to an Active Directory domain; otherwise the policies are read from GPO.

Software\Policies\Chromium\ExtensionInstallWhitelist
Mac/Linux preference name:
ExtensionInstallWhitelist
Supported on:
  • Chromium (Linux, Mac, Windows) since version 8
  • Chromium OS (Chromium OS) since version 11
Supported features:
Dynamic Policy Refresh: Yes, Per Profile: Yes
Description:
Allows you to specify which extensions are not subject to the blacklist. A blacklist value of * means all extensions are blacklisted and users can only install extensions listed in the whitelist. By default, all extensions are whitelisted, but if all extensions have been blacklisted by policy, the whitelist can be used to override that policy.
Example value:
Windows:
Software\Policies\Chromium\ExtensionInstallWhitelist\1 = "extension_id1" Software\Policies\Chromium\ExtensionInstallWhitelist\2 = "extension_id2"

ExtensionInstallForcelist

Configure the list of force-installed extensions
Data type:
List of strings
Windows registry location:
Software\Policies\Chromium\ExtensionInstallForcelist
Mac/Linux preference name:
ExtensionInstallForcelist
Supported on:
  • Chromium (Linux, Mac, Windows) since version 9
  • Chromium OS (Chromium OS) since version 11
Supported features:
Dynamic Policy Refresh: Yes, Per Profile: Yes
Description:
Allows you to specify a list of extensions that will be installed silently, without user interaction. Each item of the list is a string that contains an extension ID and an update URL delimited by a semicolon (;). The extension ID is the 32-letter string found e.g. on chrome://extensions when in developer mode. The update URL should point to an Update Manifest XML document as described at https://developer.chrome.com/extensions/autoupdate. Note that the update URL set in this policy is only used for the initial installation; subsequent updates of the extension will use the update URL indicated in the extension's manifest. For each item, Chromium will retrieve the extension specified by the extension ID from the update service at the specified update URL and silently install it. For example, lcncmkcnkcdbbanbjakcencbaoegdjlp;https://clients2.google.com/service/update2/crx installs the Google SSL Web Search extension from the standard Chrome Web Store update URL. For more information about hosting extensions, see: https://developer.chrome.com/extensions/hosting. Users will be unable to uninstall extensions that are specified by this policy. If you remove an extension from this list, then it will be automatically uninstalled by Chromium. Extensions specified in this list are also automatically whitelisted for installation; the ExtensionsInstallBlacklist does not affect them. If this policy is left not set the user can uninstall any extension in Chromium.
Example value:
Windows:
Software\Policies\Chromium\ExtensionInstallForcelist\1 = "lcncmkcnkcdbbanbjakcencbaoegdjlp;https://clients2.google.com/service/update2/crx"

Data type:
List of strings
Windows registry location:
Software\Policies\Chromium\ExtensionInstallSources
Mac/Linux preference name:
ExtensionInstallSources
Supported on:
  • Chromium (Linux, Mac, Windows) since version 21
  • Chromium OS (Chromium OS) since version 21
Supported features:
Dynamic Policy Refresh: Yes, Per Profile: Yes
Description:
Allows you to specify which URLs are allowed to install extensions, apps, and themes. Starting in Chromium 21, it is more difficult to install extensions, apps, and user scripts from outside the Chrome Web Store. Previously, users could click on a link to a *.crx file, and Chromium would offer to install the file after a few warnings. After Chromium 21, such files must be downloaded and dragged onto the Chromium settings page. This setting allows specific URLs to have the old, easier installation flow. Each item in this list is an extension-style match pattern (see https://developer.chrome.com/extensions/match_patterns). Users will be able to easily install items from any URL that matches an item in this list. Both the location of the *.crx file and the page where the download is started from (i.e. the referrer) must be allowed by these patterns. ExtensionInstallBlacklist takes precedence over this policy. That is, an extension on the blacklist won't be installed, even if it happens from a site on this list.
Example value:
Windows:
Software\Policies\Chromium\ExtensionInstallSources\1 = "https://corp.mycompany.com/*"
Linux:
["https://corp.mycompany.com/*"]
Mac:
<array> <string>https://corp.mycompany.com/*</string> </array>

See the Chromium extensions documentation for more information on these types. Note that this policy also affects extensions and apps to be force-installed via ExtensionInstallForcelist. If this setting is configured, extensions/apps which have a type that is not on the list will not be installed. If this settings is left not-configured, no restrictions on the acceptable extension/app types are enforced.

PowerManagementIdleSettings

Power management settings when the user becomes idle
Data type:
Dictionary
Supported on:
  • Chromium OS (Chromium OS) since version 35
Supported features:
Dynamic Policy Refresh: Yes, Per Profile: No
Description:
Configure power management settings when the user becomes idle. This policy controls multiple settings for the power management strategy when the user becomes idle. There are four types of action: * The screen will be dimmed if the user remains idle for the time specified by |ScreenDim|. * The screen will be turned off if the user remains idle for the time specified by |ScreenOff|. * A warning dialog will be shown if the user remains idle for the time specified by |IdleWarning|, telling the user that the idle action is about to be taken. * The action specified by |IdleAction| will be taken if the user remains idle for the time specified by |Idle|. For each of above actions, the delay should be specified in milliseconds, and needs to be set to a value greater than zero to trigger the corresponding action. In case the delay is set to zero, Chromium OS will not take the corresponding action. For each of the above delays, when the length of time is unset, a default value will be used. Note that |ScreenDim| values will be clamped to be less than or equal to |ScreenOff|, |ScreenOff| and |IdleWarning| will be clamped to be less than or equal to |Idle|. |IdleAction| can be one of four possible actions: * |Suspend| * |Logout| * |Shutdown| * |DoNothing| When the |IdleAction| is unset, the default action is taken, which is suspend. There are also separate settings for AC power and battery.

Specifies a list of plugins that user can enable or disable in Chromium. The wildcard characters '*' and '?' can be used to match sequences of arbitrary characters. '*' matches an arbitrary number of characters while '?' specifies an optional single character, i.e. matches zero or one characters. The escape character is '\', so to match actual '*', '?', or '\' characters, you can put a '\' in front of them. If you enable this setting, the specified list of plugins can be used in Chromium. Users can enable or disable them in 'about:plugins', even if the plugin also matches a pattern in DisabledPlugins. Users can also enable and disable plugins that don't match any patterns in DisabledPlugins, DisabledPluginsExceptions and EnabledPlugins. This policy is meant to allow for strict plugin blacklisting where the 'DisabledPlugins' list contains wildcarded entries like disable all plugins '*' or disable all Java plugins '*Java*' but the administrator wishes to enable some particular version like 'IcedTea Java 2.3'. This particular versions can be specified in this policy. Note that both the plugin name and the plugin's group name have to be exempted. Each plugin group is shown in a separate section in about:plugins; each section may have one or more plugins. For example, the "Shockwave Flash" plugin belongs to the "Adobe Flash Player" group, and both names have to have a match in the exceptions list if that plugin is to be exempted from the blacklist. If this policy is left not set any plugin that matches the patterns in the 'DisabledPlugins' will be locked disabled and the user won't be able to enable them.

Dynamic Policy Refresh: No, Per Profile: Yes
Description:
If set to enabled this policy forces the profile to be switched to ephemeral mode. If this policy is specified as an OS policy (e.g. GPO on Windows) it will apply to every profile on the system; if the policy is set as a Cloud policy it will apply only to a profile signed in with a managed account. In this mode the profile data is persisted on disk only for the length of the user session. Features like browser history, extensions and their data, web data like cookies and web databases are not preserved after the browser is closed. However this does not prevent the user from downloading any data to disk manually, save pages or print them. If the user has enabled sync all this data is preserved in his sync profile just like with regular profiles. Incognito mode is also available if not explicitly disabled by policy. If the policy is set to disabled or left not set signing in leads to regular profiles.

Wallpaper image
Data type:
External data reference

  • Chromium OS (Chromium OS) since version 35
Supported features:
Dynamic Policy Refresh: Yes, Per Profile: Yes
Description:
Configure wallpaper image. This policy allows you to configure the wallpaper image that is shown on the desktop and on the login screen background for the user. The policy is set by specifying the URL from which Chromium OS can download the wallpaper image and a cryptographic hash used to verify the integrity of the download. The image must be in JPEG format, its file size must not exceed 16MB. The URL must be accessible without any authentication. The wallpaper image is downloaded and cached. It will be re-downloaded whenever the URL or the hash changes. The policy should be specified as a string that expresses the URL and hash in JSON format, conforming to the following schema: { "type": "object", "properties": { "url": { "description": "The URL from which the wallpaper image can be downloaded.", "type": "string" }, "hash": { "description": "The SHA-256 hash of the wallpaper image.", "type": "string" } } } If this policy is set, Chromium OS will download and use the wallpaper image. If you set this policy, users cannot change or override it. If the policy is left not set, the user can choose an image to be shown on the desktop and on the login screen background.
